Weather in December
Temperature
The beginning of December records an average high-temperature of a tropical 33.8°C (92.8°F), almost echoing the conditions of the previous month. During the month of December, an average low-temperature of 23.9°C (75°F) is recorded.Heat index
For December, the heat index is computed to be a scorching 43°C (109.4°F). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.Note that heat index values are valued for light wind and location in the shade. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
